Serial Attached SCSI (SAS) 10K RPM or 15K RPM Hard Drive:High-end hard drives require a high-end storage bus for optimal performance. SAS hard drives offer compelling elements of the SCSI and SATA worlds in a single efficient design. SAS is an excellent standard for workstation environments requiring extremely high performance and reliability. It supports the traditional SCSI command structure so it can work with SCSI software tools. In addition, SAS is a bidirectional bus, meaning data can be routed in both directions, yielding a higher number of simultaneous data transfers to and from multiple devices than SATA hard drives.

Solid-State Drives (SSDs):SSDs provide the best overall level of storage performance. SSDs have no moving parts so their speed is not measured in RPM. In addition to offering higher performance, SSDs are also more durable, more reliable, and operate cooler and quieter than standard hard drives.
